'6 Claims. (Cl. 126190) This invention relates to cooking ranges, andmore particularly to means for making a seal between the oven door andthe front wall of a cooking range when the door is closed.

Among the several objects of the invention may be noted the provisionor" an improved means for making a tight seal between the oven door andthe front wall of a cooking range comprising heat-resistant sealingstrips and means for mounting the strips so that they are readilyremovable and replaceable when necessary without requiring disassemblyof any parts of the range; and the provision of sealing means of theclass described which is economical and easy to install on a range.Other objects and features will be in part apparent and in part pointedout hereinafter.

The invention accordingly comprises the constructions hereinafterdescribed, the scope of the invention being indicated in the followingclaims.

In the accompanying drawings, in which one of various possibleembodiments of the invention is illustrated,

Fig. 1 is a front elevation of a range equipped with sealing means ofthis invention for the oven door of the range, the door being shownopen;

Fig. 2 is an enlarged vertical cross section taken on line 22 of Fig. 1;and,

Fig. 3 is an enlarged vertical cross section taken on line 3--3 of Fig.1.

Corresponding reference characters indicate corresponding partsthroughout the several views of the drawings.

Referring to the drawings, there is indicated at 1 a cooking rangehaving a top 3, side walls 5 and a front wall 7. The front wall has arectangular opening 9 for access to the oven chamber 11 of the range. At13 is indicated the oven door. This is pivoted on a horizontal axisadjacent the lower edge of the opening 9 for swinging movement between aclosed position extending vertically upward and confronting portions ofthe front wall 7 surrounding the opening 9, and an open positionextending forward from the range. The door may be pivoted in anysuitable conventional manner, details of the hinge arrangement not beingmaterial so far as this invention is concerned. Reference may be made tothe copending coassigned application of Almer H. Brodbeck for Door,Serial No. 559,207, filed January 16, 1956, for door details.

In accordance with this invention, means is provided for making a tightseal between the door 13 and the front wall 7 of the range when the dooris closed. This sealing means comprises two vertically extending sealingstrips each designated 15 mounted on the front wall of the range atopposite sides of the opening 9, and a horizontally extending sealingstrip 17 extending between the vertical strips 15 above the opening 9.These strips 15 and 17 are formed of a resilient, slippery,heat-resistant material, preferably silicone rubber, which is adapted towithstand a temperature of 600 F., for example. The strips 15 and 17 areof identical cross section, each having a resilient bead portion 19 ofhollow generally semicircular shape in cross section and a rib portion21 of T-shape in cross ssection projecting from the flat side of thesemicircular bead portion 19. The T-shaped rib portion 21 is of solidcross section. The flat side of the semicircular bead portion 19 iswider than the head portion of the T-Shape of the rib.

Each of the strips 15 and 17 is removably mounted in a strip-retainingchannel member of C-shape in cross section. Thus, there are twovertically extending channel members at opposite sides of the opening 9,each designated 23, and a horizontally extending channel member 25 ofG-shape in cross section above the top of the opening 9. The members 23extend from below the level of the bottom of the opening 9 to above thelevel of the top of the opening 9. The member 25 extends between members23 from near one member 23 to near the other. The front wall 7 is formedwith grooves 23a receiving members 23 and a groove 25a receiving member25. The channel members 23 and 25 are generally identical, each beingformed of sheet metal and having loops 27 struck out from its back wallor web extending through holes 29 in the front wall 7 of the range. Thechannel members are secured in position with their open sides forward inthe channel members so that the strips are slidably keyed in the channelmembers. The stem portions of the T-shape of the strips project out ofthe channel members through the open sides of the channel members, andthe resilient bead portions 19 of the strips are disposed outward of thechannel members for engagement by the door 13 when the latter closes.The strips, being slippery, are readily longitudinally slidable in thechannel members for endwise removal therefrom. Replacement strips arereadily inserted in the channel members by longitudinally sliding theminto the channels. The lower ends of the side channels 23 may be pinchedas indicated at 33 after the strips are in place to keep the strips fromsliding downward out of these channels under their own weight.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As various changes could be made in the above constructions withoutdeparting from the scope of the invention, it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitingsense.

We claim:

1. in a cooking range having an oven, a front wall provided with arectangular opening for the oven and a door pivoted on a horizontal axisadjacent the lower edge of the opening for swinging movement between aclosed position extending vertically upward and confronting portions ofthe front Wall surrounding the opening and an open position extendingforward, means comprising vertically extending sealing strips at thesides of the opening and a horizontally extending sealing strip abovethe opening for making a seal between the door and the front wall whenthe door is in closed position, the vertical strips being separate fromone another and the horizontal strip being separate from the verticalstrips, vertically extending strip-retaining channel members of C shapein cross section secured on the front face of the front wall at oppositesides of the opening, and a horizontally extending strip-retainingchannel member of C- shape in cross section secured on the front face ofthe front wall between said vertically extending channel members abovethe opening, the open sides of all of said channel members beingdirected forward, said strips having rib portions received in thechannel members whereby the strips are slidably keyed in the channelmembers, and resilient bead portions outward of the channel members forengagement by the door, said strips being longitudinally slidable in thechannel members for endwise removal therefrom.

2. In a cooking range as set forth in claim 1, said strips being made ofheat-resistant silicone rubber which is slippery so that each strip maybe readily removed from its respective channel member by longitudinallysliding it endwise out of one end of the respective channel member.

3. In a cooking range as set forth in claim 1, each of said channelmembers being made of sheet metal and having loops struck out from itsback wall extending through holes in the front wall of the range, andbeing secured in position by means of spring clips received in the loopson the inside of the front wall.

4.

5. In a cooking range as set forth in claim 4, the flat side of thesemicircular resilient head portion being wider than the head portion ofthe T-shape.

6. In a cooking range having an oven, a front Wall provided with arectangular opening for the oven and a door pivoted on an axis adjacentone edge of the opening for swinging movement between a closed positionwith respect to the opening and confronting portions of the front wallsurrounding the opening and an open position extending forward, meanscomprising first and second sealing strips extending along the two sidesof the opening at right angles to the door axis and a third sealingstrip extending along the side of the opening opposite the door axis formaking a seal between the door and the front wall when the door is inclosed position, the strips being separate from one another, first andsec ond strip-retaining channel members secured on the front face of thefront wall extending along said two sides of the opening, and a thirdstrip-retaining channel member secured on the front face of the frontWall extending between said first and second channel members along theside of the opening opposite the door axis, said strips having ribportions received in the channel members whereby the strips are slidablykeyed in the channel members, and resilient bead portions outward of thechannel members for engagement by the door, the third channel memberbeing shorter than the distance between the first and second channelmembers, said strips being longitudinally slidable in the channelmembers for endwise removal therefrom.
